Abstract:The seepage action on the bottom of a pier resting on a porous elastic seabed was obtained by numerical method. The seabed is assumed to be homogeneous, isotropic and linearly elastic porous medium, and can be described by Darcy's law, and the pore water is assumed to be compressible. The governing equations are Biot consolidation equation and storage equation. Considering the wave force acting directly on the pier, the seepage force and soil skeleton displacement were computed by iterative calculation with the motion of the pier. In the calculating process, it is divided into a diffraction problem and a radiation problem. Superposition of two solutions gives the final result.
